Tooth eruption chart
When should teeth start to be lost or new teeth grow?
At birth people usually have 20 baby (primary) teeth, which start to come in (erupt) at about 6 months of age. They fall out (shed) at various times throughout childhood. By age 21, all 32 of the permanent teeth have usually erupted.
My child’s baby teeth are still present and the adult teeth are starting to come through - is this a worry?
This is quite common. It's often a sign that the mouth won't have enough room for the permanent teeth. See your dentist. Don't upset your child by saying the dentist will need to take teeth out. Let the dentist make the decision. If removing baby teeth won't benefit the child in the long term the dentist may leave nature to take its course
